FEED-CUTTER.

FJPECIFICATION forming part of Letters Patent No. 346,200, dated July 2'7, 1886.

Application filed July 29, 1885. Serial No. 172,957. (No model.)

To all whom it may concern.-

Be it known that I, ADOLPH HAMACEK, of Ahnapee, in the county of Kcwaunee and State of lVisconsin, have invented a new and Improved Feed-Cutter, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved machine for cutting hay, straw, and like material for feeding purposes.

The invention consists in the arrangement and combination of parts and details, as will be fully described and set forth hereinafter, and pointed out in the claims.

Reference is to be had to the accompanying drawings,forming a part of this specification,in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved feedcutter, parts being broken out and others shown in section. Fig. 2 is a longitudinal sectional elevation of the same. Fig. 3 is a plan view, parts being broken out and others shown in section. Fig. 4 is a cross-sectional elevation ofthe same on the line x 00, Fig. 3. Fig. 5 is aside view of the rear part of the box, showing the gearing for driving the cutter by power. Fig.6 is a side elevation of one ofthe side plates inclosing the feeding mechanism. Fig. 7 is a side view of one of the slides in which the upper roller is journaled. Fig. 8 is a perspective view of the fixed knife. Fig. 9 is a cross-sectional view of the cover for the upper feed-roller. Fig. 10 is a detail view of one of the shafts, and the means for preventing it from moving in the direction of its length.

The box A, for receiving the hay, straw, or other like material to be cut, is secured on a frame, A, and is fiared toward its rear end, so that the hay, &c., will be compressed as it moves toward the front. In front of the front end of the bottom of the box a longitudinallyribbed feed-roller, B, is j ournaled in side plates, 0, secured to the frame at the front ends of the sides of the box A, the said side pieces being provided with downwardly and outwardly projecting lugs C, forming boxes for the ends of the shaft of the roller B. A longitudinally-ribbed feed-roller, D, is journaled in boxes D, formed on bars D", provided with slots D, through which the boxes of the lower roller can pass. The boxes D of the roller D slide in vertical grooves G in the side pieces, 0. The upper ends of the bars D are connected by a cross-bar, D, parallel with the rollers D B, and the lower ends of the bars D are connected by links E to the forked end E ofa lever, E pivoted to the uprights of the frame A and having notches in its top edge at the swinging end, from which notched end aweight, F, is suspended.

To the bottom surface of the bar D, uniting the bars D a curved top, G, is secured,which is above the roller D, and from the said bar Dcurved arms G project downward in front of the roller D, to the lower ends of which arms the presser-plate H is secured, which is slightly inclined downward and outward. This construction is shown in Fig. 2; but, if desired," a presser-roller, H, may be provided in place of the presser-plate H, as shown in Fig. 9. The weight F on the lever E can pull the upper roller down, so that the boxes D can rest on the bottoms of the recesses 0 The rollers D and B will then be their normal distances from each other. \Vhcn hay or straw is fed in between the two rollers, it forces the upper roller upward more or less. A deflector or inclined top plate, I, is secured to the top of the box A at the front end, and projects over the top G, above the roller D, as shown.

In front of the roller B a bottom cutter, J, is secured on a bar, J, uniting the bottom edges of the side plates, 0, the upper surface of the cutter J being inclined from the roller B upward and outward.- The outer edge of the cutter J is flush-with the rounded front edges of the side pieces, 0. The beveled cutter J and the presser-plate H are inclined toward each other from the rollers toward the front end of the machine, and gradually compress the hay or straw as it passes between them. The main driving-shaft K, journaled in the frame at the side of the box, carries a beveled pinion, K, on its rear end, which e11- gages with a bevel cog-wheel, K on a shaft, K, having a crank, K", provided with a handle, whereby, by turning the shaft K, the main driving-shaft K is revolved.

On the front end'of the shaft K, which pro jects beyond the front of the frame of the machine, a cutter-wheel,L, is mounted, which has spokes L, and on two diametrically opposite spokes the blades L are bolted, the cuttingedges of the blades being rounded on convex lines. The said blades are so arranged that their cutting-edges are in close proximity to the cutting-edge of the bottom cutter, J.

On the ends of the shafts of the rollers D and B the toothed wheels M and N, respectively, are mounted, and are arranged on opposite sides of a worm, O, on the shaft K, the upper wheel, M, engaging with the worm O at its bottom, and the lower wheel, N, engaging with the worm at its top, whereby the said wheels are revolved toward each other. The toothed wheels M N andthe worm O are surrounded by a metal casing, P, secured to one of the bars D and the lower part of the lower toothed wheel N is surrounded by a casing, Q, containing oil, into which the lower wheel, N, dips and carries the oil to the worm 0, from which it passes to the wheel M, whereby all these parts are thoroughlylubricated. The casings 1 Q also prevent parts of the straw, hay, or other feed from passing in between the teeth of the wheels M and N and the worm O, and consequently clogging the said parts.

To prevent the shaft K or the shaft K from shifting in the =dir-ection of its length, it is provided with annular grooves, 7c, for receiving the ends of binding-screws Z.

\Vhen it is desired to run the machine by power, the pinion It is mounted loosely on the shaft K, and is provided with a clutch-collar, BC. The said pinion engages with the cogwheel S on a shaft, S, and is driven from an engine, horse-power, or any other suitable motor. A sliding clutch collar, T, is arranged on the square part K of the shaft K, and is adapted to engage with the clutch-collar R on the pinion It. The clutch-collar T is shifted by means of a lever, U, having an upwardly-projecting arm or pin, U, which passes into a groove of the clutch-collar T.

a set forth.

The operation is as follows: The hay or straw is placed in the box A and between the feed-rollers B D, which draw it in the direction of the arrow a and force it through the space between the fixed blade J and the top.

claim as new, and desire to secure by Letters Patent, is-

1. In a cutter, the box A,the side plates, 0,

formed withvertical slots 0 and bearings C, projecting from their outer sides below and in vertical alignment with the slots'G, and the roller B, journaled in said bearings, in combination with the bars D, having inward-projecting bearings D fitting in the slots 0" and slots D in vertical alignment with the bear ings D, and receiving the bearings O, the upper feed-roller, D, journaled in the bearings D, the counterbalanced lever E, and links E, connecting it with the lower ends of the bars D", substantially as set forth.

2. The combination, with the boxA, of the lower feed-roller,B,journaled in fixed bearings, the upper feed-roller, D, vertically movable bars Dflprovided with bearings for said roller D,the cross-bar D", connecting the said vertically-movable bars D ,the cover G, secured to the bar D" over the upperfeed-roller, armsG, curved downward and inward from the crossbar D*, the presser-roller H on the free ends of said arms, the fixed knife J below the roller H,

3. The combination, with the upper and lower feed-rollers, D B, and the toothed wheels M N, of the shaft K,the worm O, meshing with the said wheels, the casing P,open at its lower I end and covering the said gearing,and the oilvessel Q, open at its top and registering with the open end of the casing P, and receiving the lower part of the wheel N, substantially as ADOLPI-I IIAM CEK-L.
